Did not look at the rotational sensor close enough. In that case, scalling down the MUX
to a 16 channel will free up PORT C. The Rotational sensor or Fiber-optic can use PORT C
for rotational input. This assumes that one motor is running the forward/reverse.
Got another thought. Can the motor outputs drive two motors??
BTW, I have to go out of the country for a while, due to a work emergency. I will be gone
a few weeks, so may not read your replies for a while.
